Translation and cross-cultural adaptation of the International Hip Outcome Tool (iHOT) into Portuguese

OBJECTIVE: iHOT12/33 is an outcome tool designed for young patients with hip problems. The objective of this study is to translate and establish a cross-cultural adaptation of this questionnaire to Portuguese. METHOD: The Guillemin guidelines were followed for the translation and cross-cultural adaptation consisting on: translation, back-translation, prefinal version, administration of the Questionnaire, and editing of the final version. RESULTS: The prefinal version was applied to 30 young patients with hip problems. Some difficulties in understanding some of the words and expressions were noted, and these were replaced with simpler ones, achieving the patient's full acceptability in the final version of the Questionnaire. CONCLUSION: The creation of the Brazilian version of the International Hip Outocome Tool (iHOT) 12/33 enables this questionnaire to be used in the evaluation of patients with hip problems in Brazil, and was clearly understood, with good acceptance by the patients tested. Level of evidence II - Development of diagnostic criteria on consecutive patients (with universally applied reference "gold" standard).
